... at up to 50km/h. While all this is happening a distinct "eye" is forming in the centre of the Cyclone. This "eye" unlike the rest of the Cyclone is completely calm and is not windy at all. Cyclone Tracy was the most destructive cyclone recorded to hit Australia since white settlement in 1788 (the Bathurst Bay killed 300 people but didn't reach land). Cyclone Tracy hit the coastal city of Darwin on Christmas Day 1974. Although people had warning on New Year's Day about Cyclone Tracy, they were busy preparing for Christmas and thought that the cyclone would pass away just like Cyclone Selma had done three weeks before. Cyclone Tracy came roaring down the Arafura ...

... cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment. The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rive ...

... of the reason for this is the fact that people that exercise tend to have more healthy lifestyles, which include lower levels of alcohol use and lower fat diets. My stepfather had coronary heart disease. He talked about it freely before he passed away. Over the course of 10 years he had two triple bypass surgeries. He believed he contracted the disease due to poor diet, smoking and a family history of the disease. Throughout the entire time his outlook remained very positive. There were several dramatic changes that the disease caused. He quit smoking after the first heart attack. On the first year after surgery many things went on like they had before the surgery. ...

... sugar cane fields in Hawaii became the breeding grounds for rats. Farmers released mongooses to kill the rats. They also began to eat the nene chicks and eggs. Roy Blackshire runs a program that places captive born nenes into the wild. This program, once a success, is now causing chaos in the nene population. A single pair of nenes were taken from the wild and bred in captivity. Later two more birds were added. The chicks were released into the wild and the program continued. Though there are several dozen nenes released from captivity, there is still little increase in the wild population. The inbreeding between birds is not allowing for any genetic diversity t ...

... years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to "programming" rules that the user must memorize, all ordinary arithmetic operations can be performed. The next innovation in computers took place in 1694 when Blaise Pascal invented the first "digital calculating machine". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal's father who was a tax collector. In the early 1800's, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-di ...

... its route to the cortex of the kidney. Once in the cores the vessels become even smaller forming capillary balls called Glomeruli. The Glomeruli pick up certain substances that travel through the Glomeruli capillary wall and enter the proximal kidney tubules, creating an ultra filtration systems, which eventually becomes urine. Substances that do not filter through the Glomeruli wall continue through the Kidneys blood supply, allowing it to reenter the renal vein and inferior vena cava. On a normal basis only small molecular weights (such as sugars, fatty acids, water, etc.) Are filtered at the renal Glomeruli. Larger waste such as proteins and hormones do n ...

... effective. Biological weapons can ve traced back to Exodus when God placed the ten plagues upon the Egyptians, as a result of Pharaoh’s refusal to free the Jews from slavery. These plagues included blood, frogs, vermin, flies, murrain, boils, hail, locusts, darkness, and the slaying of the first born. Even though this type of warfare may have had origins as early as Exodus, the methods of making these germs is described in scientific literature and is no secret to terrorists. This germ warfare is an especially serious threat for several different reasons. The first reason is the ability of these germ agents to be undetectable to spy technology. Secondly, the w ...

... small streams the the largest resevoir, and almost everything in between. Up north the has a longer lifespan than in the south, at sixteen years old. While it may get older up north the size of the bass is larger in the south. This is so because there is more to eat. The sexual characteristics of the bass remain the same nort and south. The spawn in the spring, when water temperatures begin to move past sixty degrees fahrenheit. The spring spawning urge in a bass is set off by both water temperature and photoperiod. Photoperiod is the proportion of the day in which the bass are exposed to sunlight. As the day light hours grow longer through the spring and ...

... Chinese leader and medical expert, Sheng Nong, discovered tea as a medicinal herb in 2737 B.C. One day while he was boiling water under a tea tree, some tea leaves fell into Sheng's pot of boiling water. After drinking some tea, he discovered its miraculous powers and immediately placed tea on his list of medicinal herbs. John Blofeld, in Chinese Art of Tea, writes that ¡§it can be confidently stated that tea was known in the three kingdoms epoch (AD 222-277).¡¨ More importantly, however, ¡§tea [was] originally drunk for its medicinal properties.¡¨ (Blofeld 4) Evans links the early popularity of tea to Taoist religious practices during the Qin Dynasty (201 ...

... to dig itself out of the nest. When it is born it is the about the size of a child's hand. It eats the Portuguese Man of War, a very deadly jellyfish. It has very tough skin so it does not have to worry about getting stung by the jellyfish. It lives in the ocean all of its life and lays its eggs on the shore, when the babies are born they go on their own to their own life. The turtle lives in a type of weed which floats in the ocean drifting with the currents, the environment is very bad for the turtle since there is a lot of offshore dumping by ships, polluting the ocean. There is a total of thirteen tons of trash being dumped every one minute. The danger of the ...
